issue with 6509 switch

[imstha001]

Just a quick question. I was implementing the iBGP in core network for redundancy purpose. As I finished the implementing iBGP in all core network device. one of cisco 6509 switch start to having problem and it is not responding properly. I  quickly looked into to memory and cpu utilization and everything was normal. And I had removed the iBGP setup from network devices but still this 6509 did not came back to normal.

Ultimately I had to reboot the device and everything start to work fine.Please let me know if you have any suggestion what may be the issue.

By the way, we have multi homing eBGP with two different ISP and receiving full eBGP routing from both ISP.

We are receiving around 400K IPv4 routes.

SWITCH-6509#sh mls cef maximum-routes
FIB TCAM maximum routes :
=======================
Current :-
-------
 IPv4 + MPLS         - 512k (default)
 IPv6 + IP Multicast - 256k (default)

I have attached the network diagram. A-6509 had a problem during implementation.

What exactly means by 6509 not coming back to normal?

Is device not accessible remotely?

Console access was working? If yes r there any outputs captured during the issue?

Yes we really need more info did you collect any logging or outputs/show tech of the issue before you rebooted it otherwise its going to be very difficult to identify what exactly has happened
